Definitions
- the invention relates to an oil filter for the cleaning of lubricating oil, in particular for internal combustion engines of motor vehicles, with a filter housing arranged at least approximately upright in the installed state with a screw-on cover and an annular filter insert which can be detachably connected to the latter, an oil inlet in the filter housing for contaminated oil to the inflow space surrounding the filter insert and an oil outlet for cleaned oil from the outflow space formed by the interior of the filter insert and, furthermore, in the lower region of the filter housing a drainage duct connected to an oil collecting space for remaining in the filter housing when the filter insert is changed Oil is provided, which is automatically opened by a valve-like member each time the filter insert is changed, but is otherwise permanently closed.
- valve-like member In a known oil filter of this type (EP-PS 0314915) the valve-like member is arranged decentrally in the filter housing and is there under the action of oppositely acting compression springs, one of which acts on the valve-like member in the closing direction is supported on the filter insert .
- the force acting in the closing direction of this one compression spring disappears, so that the other compression spring acting in the opposite direction in the opening direction can actuate the valve-like member in the opening direction and thus open the opening to the discharge channel. Since the one compression spring acts asymmetrically on the filter insert, this is disadvantageously stressed asymmetrically.
- the filter insert can only be removed from the cover with difficulty.
- the aim of the invention is to provide a better design for an oil filter for cleaning lubricating oil, in which oil remaining in the filter housing is automatically drained off each time the filter insert is changed.
- a central rod is connected axially displaceably to a limited extent, which in its area near the cover has a piston-like thickening which is sealed off from the filter insert and separates the inflow space from the outflow space, and which in has the valve-like link in its lower end region which interacts with the discharge duct.
- the cover can be rotated relative to the central rod.
- the limited axial displaceability of the central rod relative to the cover can be achieved by interlocking catches on these two parts and a stroke limiter provided on one of these two parts and directed against the other of these two parts.
- this creates the possibility of providing an axial play between these two parts, which is necessary to compensate for different thermal expansions and manufacturing tolerances of the parts.
- the axial play of the center rod is further limited in the direction from the cover of the oil filter in that the valve-like member securely seals when the oil filter is closed.
- At least one compression spring can be located between the cover and the central rod be provided.
- this compression spring supports the holding of the valve-like member in the closed position during operation of the oil filter.
- this compression spring when the assembly of cover, center rod and filter insert is removed from the filter housing, with the lower end of the center rod supported at the bottom, allows the filter insert to be released (pushed off) from the piston-like thickening by pressure from above onto the cover, the compression spring being compressed.
- a compression spring can advantageously be arranged coaxially to the central rod in the area of the thickening, enclosing the stroke limiter and enclosed by the catches.
- the correct position of the filter insert can be better ensured that this is provided on its inner circumference with a support ring which is supported on an inner, cylindrical support body which is fastened in the lower part of the filter housing by a snap connection.
- the filter housing can be designed as an aluminum casting, the cover as a plastic injection-molded part and the central rod with a thickening and valve-like member as a plastic molded part.
- a standing oil filter according to DE-A-41 31 353 is also known.
- This filter is a combined main and secondary flow filter.
- the bypass filter part is formed by a housing which is integrally formed on a center rod which is rotatably connected to a screw cap.
- This housing is divisible so that a replaceable filter element can be used there.
- the center bar has two functions. One coincides with that according to the invention and consists in closing a drainage channel connected to an oil collection chamber in the manner of a valve in the lower region of the filter housing. The second function is to allow oil flowing through the bypass filter part to flow into the channel closed by the central rod through this central rod during filter operation.
- the filter insert of the main filter part is fastened in a radially slidable manner to the bypass filter part, which is firmly connected to the central rod.
- the part of the bypass filter housing onto which the main filter insert is pushed is a connection piece that is tightly inserted into the filter housing.
- a particular disadvantage of this filter is that the socket on which the filter insert of the main filter is mounted requires an additional seal in the housing. Furthermore, the surfaces on which that socket lies tight in the housing must be machined particularly, which is expensive.
- the storage of the filter insert in the invention is also structurally much simpler than that of the main flow filter insert in the previously known embodiment.
- a contact disk 9 is provided on this, which interacts with a system 10 in the filter housing 1 and thus forms a valve-like element, the passage of which is opened when the central rod 3 moves upward, specifically to a discharge channel 11 , which leads to an oil collecting space - not shown in the drawing.
- the seals 12 and 13 can alternatively also be provided on the filter insert 14, as shown in FIG. 2.
